That check is a square root sign by the way

anonymous · Answer

you need compose the functions.
F(G(x)) and G(F(X)) and if you do that and get x out from both it is and inverse function.
So this means put whatever F(x) is equal to in for x on you equation G(x). and vice versa
 
so put 2x^2-1 in for x in the equation for G(x).

*it is an inverse function.
